Longitudinal predictors of male sexual partner risk among Black and Latina women in their late thirties: ethnic/racial identity commitment as a protective factor

This study aimed to investigate predictors of male sexual partner risk among Latinas and Black women in their late thirties. We used multiple regression analysis to examine factors associated with male sexual partner risk among 296 women who participated in two waves of the Harlem Longitudinal Development Study (New York, 2011–2013 and 2014–2016). Women who experienced childhood sexual abuse had higher risk partners than those who did not [b = 0.16, 95% confidence interval (CI) = 0.06, 0.28]. Earlier marijuana use was a risk factor for partner risk in the late thirties (b = 0.12, 95% CI = 0.04, 0.27). Higher levels of ethnic/racial identity commitment mitigated this risk (b = − 0.15, 95% CI = − 0.26, − 0.04). Ethnic/racial identity commitment can be protective against male sexual partner risk among Latina and Black women who use marijuana. Further research should explore the protective role of different dimensions of ethnic/racial identity against sexually transmitted infections, including HIV.
